DLNA/Media

Hey everyone.

So, I've had Plex for a while now and I am absolutely loving it, but there is one thing that stirs me. I just moved over a lot of my music to plex, but I'm not happy about the lack of a "Play All" button, and so I have been on the search for a DLNA/UPnP player, for windows and preferably other platforms as well. 

I've tried XBMC, but I'm not a big fan of it, I just need something simple that will let me play music, something like Spotify, if that explains it easier. Can anyone recommend a nice DLNA player? If I can't find a good one, I suppose I can go code one on my own, but it would be nice to get some suggestions.

Regards,
